Abstract
Teknologi dalam bidang konstruksi terus menerus mengalami peningkatan, peningkatan bidang konstruksi tersebut mengarah kepada digunakannya beton mutu tinggi. Perkembangan teknologi dalam bidang pembuatan beton mutu tinggi mengakibatkan perkembangan pada material bahan pembentuk beton diantaranya adalah semen. Produksi semen telah mengalami pergeseran dari OPC menjadi PCC (portland composite cement) dan PPC (Portland pozzolan cement). PCC dan PPC merupakan semen dengan karakteristik teknis hampir setara semen tipe I (OPC) serta penggunaan bahan tambah water reducer Metode penelitian ini yaitu dengan membandingkan penggunaan kadar water reducer dengan persentase 0.8%, 1.2%, 1.6%, 2% perberat semen. Water reducer yang di gunakan pada metode penelitian ini adalah bahan Ligno C 491 Hasil penelitian ini rata – rata kuat tekan beton pada umur 28 hari menggunakan bahan tambah C491 dengan persentase 0,8 % sebesar 37,180 Mpa dan merupakan nilai tertinggi sedangkan nilai kuat tekan rata- rata pada penggunaan persentase 1,2 % sebesar 33,89 Mpa, nilai kuat tekan rata- rata pada penggunaan persentase 1,6 % sebesar 32,107 Mpa dan nilai kuat tekan rata- rata pada penggunaan persentase 2% sebesar 30,203 Mpa. Penggunaan water reducer lingo C491 dapat mengurangi penggunaan air pada persentase zat aditif 0.8% sebesar 2.11%, pada persentase zat aditif 1.2% sebesar 3.175%, pada persentase zat aditif 1.6% sebesar 4.23% dan pada persentase zat aditif 2% sebesar 5.29% air yang dapat dikurangi.

| Additional Information: | Technology in the construction field has increased continously, the increase in the construction field leads to the use of high quality concrete. Technological developments in the production of high quality concrete cause the material development of the forming materials concrete include cement. Cement production has a shift from OPC into PCC (Portland Composite Cement) and PPC (Portland Pozzolan Cement). PCC and PPC are cement which has almost equivalent technical characteristics to the type I of cement (OPC) and the use of material addition that is water reducer. The method of this research is to compare the use levels of water reducer with percentage 0.8%, 1.2%, 1.6%, 2% per the weight of cement. Water reducer which is used in this research method is Ligno material C 491. The results of this research is the average of compressive strength concrete in 28 days using material addition C491 with additives percentage 0.8% is amount 37.180 MPa and that is the highest value while the value of average compressive strength on the using of additives percentage 1.2% is amount 33,89 MPa, the value of average compressive strength on the using of additives percentage 1.6% is amount 32,107 MPa and the value of average compressive strength on the using of additives percentage 2% is amount 30,203 MPa. The using of water reducer lingo C491 can reduce of water using at percentage of 0.8% is amount 2.11%, at percentage of 1.2% is amount 3.175%, at percentage of 1.6% is amount 4.23% and at percentage of 2% is amount 5.29%. | |||||||||
